This study was conducted to explore a new method for imparting hydrophobicity cellulose nanofiber (CNF) using rosin sizing agent. Anionic CNF made from hardwood bleached kraft pulp by micro-grinding; this anionic then used prepare cationic through quaternization. The hydrophobization of CNFs performed adding the agent and CNFs. zeta-potentials were measured identify adsorption rate in films con...
